As a guide, it should be replaced after 6000 to 8000 hours of operation.
For the HRS012/018/024/030 option “T” (high-pressure pump) and the HRS050/060, after 8000 hours, alarm code “AL28” (pump maintenance) will be activated.
We recommend that you check for leaks and replace the mechanical seal at this time. Consider requesting maintenance from a maintenance company.

If the external piping resistance is too large, consider installing a bypass piping set. If a bypass piping set has already been installed and there is a valve, open it according to the situation and use it safely while relieving the circulating fluid discharge pressure.
